I've gotten pretty worried about the developments in video deepfakes, and I wanted to raise some awareness about what's possible with fake videos today. I put together this quiz around real vs fake videos and I've been sharing it to see how well folks do. It's hard for me to tell how easy it is to complete it, given that I was the one who made the quiz, but I think the tech has come a long way and it's pretty scary how good it'll get. Especially in the context of the upcoming elections. Would love to get your thoughts!
I think part of the problem is that I knew that some videos were fake, so I was looking to see if their lips matched other movements. If somebody is talking fast, but their body language/movements are far slower than their talking, then it’s a pretty obvious tell.
If I had just seen one of these videos out in the wild, I can’t say if I’d immediately notice they’re fake, since that wouldn’t be the first thing on my mind. I think it’s probably impossible to get an accurate test given this limitation, but this test would be good for more casual people to try (i.e., people outside of HN).
